ʻO Scandium, nona ka hōʻailona kemika ʻo Sc a ʻo kāna helu ʻātoma he 21, he metala hoʻololi palupalu, keʻokeʻo keʻokeʻo. Hoʻohui pinepine ʻia me ka gadolinium, erbium, a me nā mea ʻē aʻe, me ka liʻiliʻi o ka huahana a me ke kumukūʻai kiʻekiʻe. ʻO ka valence nui he oxidation state+trivalent.
Loaʻa ka Scandium i ka nui o nā minerala honua, akā he liʻiliʻi wale nā mineral scandium hiki ke unuhi ʻia ma ka honua. Ma muli o ka haʻahaʻa haʻahaʻa a me ka paʻakikī i ka hoʻomākaukau ʻana i ka scandium, ua hana ʻia ka unuhi mua ma 1937.
He kiʻekiʻe ka helu heheʻe ʻana o Scandium, akā ua kokoke kona ʻano me ka alumini. E like me ka lōʻihi o ka hoʻohui ʻia ʻana o kekahi mau tausani o ka scandium i ka alumini, e hoʻokumu ʻia kahi ʻāpana Al3Sc hou, e hoʻololi i ka alumini alumini a hoʻololi i nā loli ʻike i ke ʻano a me nā waiwai o ka alloy, no laila ʻike ʻoe i kāna kuleana. Hoʻohana ʻia ʻo Scandium i nā mea hoʻoheheʻe kiʻekiʻe e like me ka scandium titanium alloy a me ka scandium magnesium alloy.
E nānā kākou i kahi kiʻiʻoniʻoni pōkole e ʻike i kāna ʻike pilikino
Kūʻai nui! Kūʻai nui! Makaʻu wau e hiki ke hoʻohana wale ʻia nā mea laha ʻole ma nā mokulele mokulele a me nā rockets.
No ka poʻe meaʻai, manaʻo ʻia ka scandium ʻaʻohe mea ʻawaʻawa. Ua hoʻopau ʻia ka hoʻāʻo holoholona o nā pūhui scandium, a ua hoʻoholo ʻia ka nui o ka make o ka scandium chloride ma ke ʻano he 4 mg/kg intraperitoneal a me 755 mg/kg hoʻokele waha. Mai kēia mau hopena, pono e mālama ʻia nā pūhui scandium ma ke ʻano he mea ʻawaʻawa.
Eia nō naʻe, ma nā kula ʻē aʻe, hoʻohana ʻia nā pūhui scandium a me ka scandium e like me nā mea hoʻonani kupua, e like me ka paʻakai, ke kō a i ʻole ka monosodium glutamate i nā lima o nā chefs, kahi mea liʻiliʻi wale nō e pono ai e hoʻopau.
